This destructive bug, tliougli very small, is often so terribly in- jurious that in Illinois, Iowa, ^lissouri and Kansas it is often the author of millions of dollar's worth of damage, and that some times in a single State. What has been said of the other insects al- ready referred to as to damage to grass, corn and wheat applies to this as weli. That the chinch bug is more susceptible to sea- sonal peculiarities—especially wet—than most insects, is well known. While in very Avet years it does little damage, in c'ry years it sweeps as " with the besom of destruction "' the great prairies of the West. That it does so little damage in Michigan, New York and the East is doubtless owing to the fact that the climate is too rigorous for it. Very likely the hibernating bug succumbs to the severity of our long, cold winters. ^ This insect. Fig. 155, ^^- is hardly 4 m m long, or less than 3-^0 of an inch. Its color is black with white wings m a r k e d with black Fig. 155. Chinch bug. spots. The bugs hiber- nate in winter. In May they swarm forth in nuptial flight, and soon after the Qgg laying begins. There are two or three broods, so from June on they will be seen in all stages. The wingless larvae, the short winged and equally active and hungry pupae and the full fledged imago will all be seen sucking the juices from the i)lants at one and the same time. Neatness in farm operations, not leaving corn-stalks and rub- bish in the fields to protect and harbor the bugs in winter, is about the only remedy possible. Prof. Forbes, whose admirable researches and suggestions have been so valuable, has found th
